| 摘要 |
The present invention relates to a subminiature bone conduction speaker which vibrates bones around human skull directly and stimulates auditory nerves through bone conduction in order to help sound to be heard. Vibrations are transmitted to a part of human head and its resulting vibration power makes sound heard through the bone conduction. The bone conduction speaker of the present invention can be applied to various fields such as mobile phone, wireless phone, earring-type mobile phone, telephone and the like since it can be made a subminiature easily and improves conventional bone conduction speakers. In addition, it keeps communication private by reducing sound discharges toward outside. |
